GAP FOR ATOMIZER-BOTTLES OR THE LIKE.

Specification of Letters Patent.

Application filed January 31, 1908. Serial No. 413,510.

To all whom it may concern:

Be it known that I, THOMAS A. DE VrLBrss, a citizen of the UnitedStates, and a resident of Toledo, in the county of Lucas and State ofOhio, have invented a certain new and useful Cap for Atomizer-Bottles orthe Like; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to the caps or closure members of the classemployed for use in connection with atomizers or other like apparatus toclose the neck openings of the liquid receptacles thereof and to carrythe spraying tubes or parts, and has particular reference to metal capsor closures of the two part type.

In practice it has been customary to use two forms of metal caps of thiskind, one

form being in one piece and adapted to fit over the bottle or receptacleneck in a manner to permit a ready removal thereof, and

the other form being in two pieces and comprising a ferrule member,which is swaged on or otherwise suitably secured to the bottle neck, anda plug portion, which is threaded into the ferrule and adapted to carrythe spray parts. In order to form an air and liquid tight joint betweenthe two parts of the latterform of cap the plug is customarily providedwith a gasket-faced shoulder which seats against the outer end of theferrule member. This manner of connecting the two parts, while efficientin its operation, forms a very objectionable and unsightly form of capdue to the exposed position of the gasket member between the two metalarts.

The object of my invention is the provision of a simple and highlyefficient two part cap of this character, which is so constructed thatwhen the ferrule and plug members are in engagement the gasket member isentirely hidden fiom view and the two parts have the appearance of asingle piece, thus materially improving the appearance and enhancing thecommercial value of the article to which the cap is applied.

The invention is fully described in the following specification andillustrated in the accompanying drawings, in which,

Figure 1 is a central vertical section of one form of atomizer embodyingmy invention, Fig. 2 is a side elevation of another form of atomizerembodying the invention with a Patented Sept. 15, 1908.

portion of the ferrule member of the cap broken away, and Fig. 3 is acentral longitudinal section of a modified form of the ferrule member.

Referring to the drawings, 1 designates the bottle or liquid receptacleof the atomizer or other apparatus with which the cap embodying theinvention is associated, and 2 is the ferrule member of the cap, whichis securely fixed to the bottle neck by shrinking or swaging it thereon.

The ferrule 2 has its outer end preferably, but not necessarily,contracted over the end of the bottle neck to reduce its diameter, asshown at 3, and has its outer end portion 4 rolled inwardly uponitselfso that it lies in substantial parallelism with the body por tion of theferrule with its edge facing the opposite end of the ferrule and forminga shoulder or stop below the end of the ferrule body against which theinternally threaded bushing-member or ring 5 seats. The bushing 5 issecured within the outer end portion of the ferrule by solder, or in anyother suitable manner, and has its opening of less diameter than theouter end opening of the ferrule to form an inner annular seat at thebase of the inturned end portion 4 thereof against which the gasketfaced shoulder of the plug member of the cap abuts when said plug isscrewed home within the bushing.

The plug member of the cap comprises the threaded stem portion 6, whichis adapted to thread into the bushing 5, and the head or enlargedportion 7, which is of suitable diameter at its base to adapt it to fitwithin the socket of the ferrule forced by its inturned end and thebushing 5 and shoulder against the top of said bushing. WVhile this plugshould be provided with the stem and enlarged portion as stated, itsgeneral form may be changed as the type of atomizer to which it isapplied or the arrangement of its liquid and air-tubes may require. Toprovide a liquid-tight joint between the ferrule and plug the usual ringgasket 8 is disposed between the shoulder of the head 7 and the bushingtop, said gasket being of suitable size to fit within the ferrulesocket, and its thickness is preferably such that when the plug isscrewed home the gasket will be pressed out ofsight within the socket bythe coaction therewith of the plug shoulder, thus giving the ferrule andplug the appearance of a single piece.

In Fig. 3 the ferrule member is shown as having its outer end portionturned inwardly in such a manner as to provide the countersunk seat aand the contracted threaded opening 1) into which the stem of the plugmay thread, thus providing a simple and cheap form of ferrule andeliminating the use of the separate bushing piece shown in the otherviews.

It is apparent that my invention not only forms a two part cap of thecharacter de scribed which is pleasing to the eye, but one which has itsparts so formed and connected as to provide a strong, tight andpractically invisible joint between them thus materially enhancing thecommercial value and practicability thereof.

I wish it understood that I do not wish to be restricted. to the exactdetails of construction and arrangement of the parts shown anddescribed, as obvious modifications will occur to persons skilled in theart.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,-

1. The combination with a bottle, of a ferrule incasing the neck thereofand having its outer end portion turned inwardly upon itself, said outerend portion being provided with an inner annular seat 'which iscountersunk relative to the outer end of the ferrule and provided with athreaded opening, and a plug member threaded into said opening andhaving a gasket-faced portion for seating against said seat.

2. A cap of the class described, comprising a ferrule having one endportion rolled inwardly, a separate bushing piece secured within theferrule in abutment with the inturned end thereof and forming an annularinternal shoulder which is countersunk relative to the ferrule end, agasket disposed on said shoulder, and a plug having an enlarged portionfor seating within the ferrule end against said gasket and a reducedportion which cooperates with the bushing to effect a tightening of theenlarged portion against the gasket.

In testimony whereof I have hereunto signed my name to thisspecification in the presence of two subscribing witnesses.
